BatteryThe unit comes with a NiMH 12V/1,5Ah battery. Battery replacement or discharge does not result in loss of memory information. A comprehensive manually or automatically activated acoustic and LED battery status control, besides the high level transmit side tone, gives the operator easy to under- stand battery status information. This is especially helpful in extreme operating conditions.

AudioThe audio volume is adjustable in seven steps to control tones for receiving, transmitting and battery status warning. External microphone sensitivity can be easily set in seven steps. Both the built-in microphone and loudspeaker are switched OFF, when an external microphone is connected to the multifunction 10-pole accessory socket.
